Cape Byron Marine Park, Marine conservation area in northern New South Wales, Australia.
Cape Byron Marine Park is a protected ocean area along the northern coast of New South Wales spanning 22,000 hectares of water between Brunswick Heads and Lennox Head. The park contains rocky reefs, sandy bays, and seagrass beds that support hundreds of fish species and other marine animals.
The New South Wales government established this marine park in 2002 to protect the northern coast's biodiversity. In 2006 it received a zoning system that divided the area into sections with different rules, strengthening ecosystem protection.
The Bundjalung and Jali peoples have lived along these waters for thousands of years and their connection to the sea remains visible in how the park is managed today. Local communities still gather here for fishing and cultural activities that tie them to their heritage.
The park is easily reached from several beach access points along the coast, with Byron Bay being a popular starting point. Different zones have different rules for swimming, snorkeling, and diving, so check local guidelines before you go.
The East Australian Current brings warm water from the north that meets cool southern currents, creating a unique mixing zone. This clash supports around ten different marine ecosystems in the same area, allowing tropical and cooler-water species to live together.
